Customer Reviews
Love my new RO system!
My new Reverse Osmosis Water Filtration System is fantastic! Installation was a breeze for my husband, even with just basic tools. The water quality is so crisp and clean, it's a noticeable difference from our old pitcher filter. I can't believe I waited this long to upgrade. I'm telling all my friends about Expresswater, and I'll definitely be buying my replacement filters from them when the time comes!
Got the TDS Meter
Needed a TDS Meter. Ordered it. Arrived in 4 days. Works as expected. Reads were consistent. Simple, effective purchase.
Good filter, slow shipping
I purchased the Whole House Water Filtration System. The system itself seems robust and the filtered water quality throughout the house is noticeably better, especially for showering. Installation was a bit more involved than I anticipated, but manageable if you're handy. My main gripe was the shipping time; it took over a week to arrive, which felt a bit long compared to other online purchases I've made recently. Also, the instructions could use slightly larger diagrams for us older folks. But once it was in, the performance has been solid, and the value for the price seems fair.
Good system, detailed instructions
I ordered the Reverse Osmosis Water Filtration System a few weeks ago. The ordering process on the website was straightforward; I had no issues finding the right model for my needs. Shipping took about 6 days to get to me in Arizona, which was within their estimated timeframe. When it arrived, everything was well-packed and there was no damage. Installation was surprisingly easy for a DIY project. The instructions provided were very clear, with good diagrams. I did have a question about the drain saddle connection, so I called customer support. They answered quickly and the representative was helpful, clearing up my confusion in just a few minutes. The water quality is much better now, and the flow rate from the faucet is decent. Overall, I'm satisfied with the product and the support I received.
Consistent quality, easy to swap
This is my third time buying the Replacement Filter Sets for my Reverse Osmosis system. Each time, the filters arrive quickly and are exactly what I expect. I've been using their systems for years and they're always reliable. Swapping out the old filters for the new ones is a simple process, takes me about 15 minutes. It's why I keep coming back – I know what I'm getting, and it works.
Water tastes way better
Got the Under Sink Water Filter a while back because our tap water was gross. Super easy to order, and it got here pretty fast. My husband installed it himself, said it wasn't too bad. Now our coffee and just drinking water taste so much better. Definitely a good buy, happy with it.

Anyone know if you can stack discount codes? Got a first-time buyer one but also saw something for replacement filters.
Thinking of getting one of their RO systems. Are they really easy to install for someone who's not super handy?
